Description
Technical field
The utility model relates to a kind of field of security identification of automobile driver, particularly a kind of fatigue of automobile driver safe recognition system field of driving.
Background technology
The research of driving fatigue is divided into subjective and objective two kinds of methods, subjective research technique has that subjective bar is tabled look-up, chaufeur oneself record, sleep habit questionnaire Stamford are slept yardstick table four kind.Body temperature (obtaining with infrared ray ear probe) when objectively method has electroencephalogram (clinic electrode), electroculogram, electromyogram, respiratory air flow (twang sensor), effect of breathing (thoracic cavity portion sensor), arterial blood oxygen saturation (finger probes) and cardiogram method of measurement such as (when driving and sleeping).Although these methods are more accurately, owing to these methods generally are before driving or drive the back and measure, be leading or hysteresis, be non real-time.Moreover it also is very difficult settling complicated detector in the limited space of operator's compartment.And the state of mind that chaufeur breaks away from operator's compartment or do not enter operator's compartment is different, and accurate its result of a measurement of instrument also can be subjected to very big influence again.
The utility model content
For overcoming the above problems, the utility model discloses the safe recognition system that a kind of fatigue of automobile driver is driven, reduced the generation of traffic accident.
The utility model adopts following technical scheme:
The safe recognition system that a kind of fatigue of automobile driver is driven, comprise master controller, the image capture module that all is connected with master controller, audio alert module and automobile brake module, described image capture module comprises the pick up camera that connects successively, A/D converter and dsp processor, dsp processor is connected with master controller, described automobile brake module comprises the speed sensor that connects successively, vehicle-state module and relay, speed sensor all is connected with master controller with relay, described audio alert module comprises voice suggestion and the annunciator that is connected, and voice suggestion is connected with master controller.
Described pick up camera is taken the facial expression of chaufeur, after the data process conversion of A/D converter that obtains after taking, send into dsp processor, dsp processor is handled image and computing, judge chaufeur and whether be in fatigue state and tired grade, and the result imported master controller, master controller is handled data later by dsp processor and is sent corresponding instruction.
Described speed sensor is used for implementing the motoring condition of the current automobile of monitoring, described relay is the electromagnetic relay of circuit series connection between ignition lock and primary ignition coil, and open close by the external aerotron control relay of master controller, and the open and close controlling firing circuit by described relay contact, after detecting warning and starting after the certain time, when chaufeur still was in fatigue state, master controller makes by the controller relay forced automobile to stop.
Described audio alert module has mainly entered the state of fatigue driving by annunciator prompting chaufeur, and described annunciator is that buzzer phone adopts speech chip, and chip integration has become that crystal oscillator, Mike are preposition, amplifier and automatic gain control.
The utility model compared with prior art has the following advantages: adopt pick up camera to take the facial expression of chaufeur, pass through computing and the processing of dsp processor then, realize that phonetic alarm reminds chaufeur to enter fatigue state when chaufeur enters fatigue state, suggestion is had a rest, when chaufeur still is in fatigue state after phonetic alarm has been reported to the police certain the time, master controller force disconnect oil circuit, force the automobile stop motion, in case major structure becomes traffic accident, the fatigue state that adopts pick up camera to implement the monitoring chaufeur can remind chaufeur to enter fatigue state, to reduce the generation of traffic accident.

The specific embodiment
As shown in drawings, the safe recognition system that a kind of fatigue of automobile driver of the utility model is driven, it is characterized in that mainly comprising image capture module, master controller, audio alert module and automobile brake module, described image capture module, described audio alert module, described automobile brake module link to each other with described master controller respectively; Described image capture module mainly comprises pick up camera, A/D converter and dsp processor composition, described pick up camera is taken the facial expression of chaufeur, after the data process conversion of A/D converter that obtains after taking, send into dsp processor, dsp processor is handled image and computing, judge chaufeur and whether be in fatigue state and tired grade, and the result is imported master controller, master controller is handled data later by dsp processor and is sent corresponding instruction.
Further, the safe recognition system that described a kind of fatigue of automobile driver is driven, it is characterized in that described automobile brake module mainly comprises speed sensor and relay, described speed sensor is used for implementing the motoring condition of the current automobile of monitoring, described relay is the electromagnetic relay of circuit series connection between ignition lock and primary ignition coil, and open close by the external aerotron control relay of master controller, and the open and close controlling firing circuit by described relay contact.Detect after certain time after the warning startup, when chaufeur still was in fatigue state, master controller makes by the controller relay forced automobile to stop.
Further, the safe recognition system that described a kind of fatigue of automobile driver is driven, it is characterized in that described audio alert module has mainly entered the state of fatigue driving by annunciator prompting chaufeur, described annunciator is that buzzer phone adopts that speech chip, chip integration have become that crystal oscillator, Mike are preposition, amplifier and automatic gain control.
The above; only be embodiment of the present utility model; be not that the utility model is imposed any restrictions, every any simple modification, change and equivalent structure of above embodiment being done according to the utility model technical spirit changes, and all still belongs in the protection domain of technical solutions of the utility model.
